Cotton seed has a similar structure to other oilseeds, such as sunflower seed, having an oil-bearing kernel surrounded by a hard outer hull; in processing, the oil is extracted from the kernel. Cottonseed oil is used for salad oil, mayonnaise, salad dressing, and similar products because of its flavor stability. [2]
Cottonseed hulls. The outer coverings of the cottonseed, known as cottonseed hulls, are removed from the cotton kernels before the oil is extracted. Cottonseed hulls are an excellent source of livestock feed as they contain about 8% cotton linters, which are nearly 100% cellulose. They require no grinding and easily mix with other feed sources.
The cottonseed which remains after the cotton is ginned is used to produce cottonseed oil, which, after refining, can be consumed by humans like any other vegetable oil. The cottonseed meal that is left generally is fed to ruminant livestock; the gossypol remaining in the meal is toxic to monogastric animals. Cottonseed hulls can be added to ...
Pulp and paper mills contribute to air, water and land pollution and discarded paper and paperboard make up roughly 26% of solid municipal waste in landfill sites. [11]Pulp and paper generates the third largest amount of industrial air, water, and land emissions in Canada and the sixth largest in the United States.

Besides being fibre crops, Gossypium hirsutum and Gossypium herbaceum are the main species used to produce cottonseed oil. The Zuni people use this plant to make ceremonial garments, [8] and the fuzz is made into cords and used ceremonially. [9] Flowers of Gossypium hirsutum. This species shows extrafloral nectar production. [10]
Cottonseed meal is the byproduct remaining after cotton is ginned, the oil extracted, and the seeds crushed. Cottonseed meal is usually used for animal feed and in organic fertilizers. [1] Cottonseed meal is about 40 percent protein by weight. [2] Compared to cellulose and lignin, proteins decompose rapidly and release nitrogen. [3]
